smooth a surface plot
142 views (last 30 days)
I have an array of data which I'm plotting using the surface function. I'd like to smooth the data but interp2 doesn't work since I don't have a mesh (I'm plotting data, not a function). Is there a way I can smooth this?
My code isn't much to look at:
surface = surf(P1,P2,L);
where P1, P2 and L are imported from a data file.
